The current opioid crisis is largely a problem among low-income whites and is treated as a crisis of public health, not a criminal justice issue, according to the study.

The study points the finger at the health care field for a two-fold role that includes differing access to the drugs that have channeled large amounts of drugs to low-income whites, creating widespread addiction, but a “sea of untreated pain in minority communities,” according to a U.S. News and World Report analysis of the JAMA report.

“The prescription drug crisis should really be thought of as a double-sided epidemic,” Joseph Friedman, the study’s lead author and a medical student at UCLA, told U.S. News. “Essentially, the … racism within the health care system has led to increased addiction and overdoses in low-income white areas, but also, insufficient treatment among communities of color.”

For instance, 44.2 percent of adults in impoverished, predominantly white zip codes in California received at least one opioid prescription per year compared with adults in low-income, racially diverse zip codes in the state, according to the report.

The disparity stretched beyond income boundaries too, the report indicated. For instance, 27 percent of adults in Beverly Hills were prescribed benzodiazepines compared with 5 percent of adults in predominantly Black and Latino Watts, the study showed.

“If you’re living in Compton, you’re probably not getting a lot of prescribed opioids,” David Schriger, a physician who oversaw the research, told U.S. News. “You can’t tell me there are no prescriptions for opioids, so to speak, in Compton because no one is in pain in Compton. It just defies logic.”

Researchers who contributed to the report analyzed data from 2011 to 2015 from California’s prescription drug monitoring program.
